Photograph of a worker during the archealogical excavation near the house at the Four Mile House located in Denver, Colorado. With a portion dating from 1859, Four Mile House is Denver's earliest surviving structure. The location served as the last stage stop, before entering Denver, on the Wells Fargo Butterfield Stage route between El Paso and Denver. Over the years, the current U-shaped plan evolved as three buildings were butted together to accommodate changing needs. Together, the 1859 squared log, the circa 1860s wood frame, and the 1883 brick portions reflect the evolution of rural housing during the Denver area's early settlement period. The house and several adjacent agricultural buildings are now part of a living history museum known as Four Mile Historic Park.
